The Group component is a Node component that can be used to wrap other objects for the purpose of grouping them. This allows you to transform and set the opacity and visibility of multiple 3D components in the Properties view simultaneously.
To add a Group component to your scene, drag-and-drop it from Components > Qt Quick 3D > Qt Quick 3D to the 3D view or to Navigator > View3D > Scene Environment > Scene.
If the Group component is not displayed in Components, you should add the Qt Quick 3D module to your project, as described in Adding and Removing Modules.
Select the Group component in Navigator to modify Node properties for its child components in the Properties view.
Available under certain Qt licenses.
